DIY Lego Brick Cake

If there’s one thing ALL kids love it’s Lego. They can sit and play with it for hours, putting together creations of all sizes and imaginations. It’s safe to say a Lego piece cake is going to be a hit with many! Check out how amazing this cake is that mum Carlie put together for her son’s 4th birthday. The best part? It’s easy to make yourself. Here’s how…

What You Need

  • 1 x Coles mud cakes (that’s right, you don’t even have to cook this one).
  • Buttercream
  • Lego silicone moulds
  • White candy melts
  • Food Dye

How to Make It

  1. Cut off the top of one of the Coles mud cakes and place some buttercream there. Put the second Cole mud cake on top upside down. This should give you a nice and flat top to work with!
  2. Cover both cakes in buttercream as a crumb coat. Place it in the fridge to harden. Bring out and cover again with a topcoat.
  3. Now time to prepare those Lego bricks! Split up the candy melts into different bowls (as many colours as you want to make. Add a few drops of different-coloured dye to each one.
  4. Pop in microwave one at a time and melt slowly, stopping to mix along the way.
  5. Pour melted chocolate into silicone Lego mould. It might help to do one colour at a time, wait till they are dry, and the move on with the next one. They keep for a while, so you can get this fiddly bit done ahead of time.
  6. Once moulds have set, pop out the bricks and store them in an airtight container.
  7. Have fun placing them all over the cake! You can do it any way you like, the messier the better.
Voila! Your very own DIY Lego brick cake. Pop it on a cake board and you’re ready to party! Here’s a handy DIY party planning checklist to help you out.
